Great Product

I take 3 tablets 20 minutes before training. Mainly cardio, but some weight training. They will get you sweating, and I mean sweating! Gibe me that extra push and make me leave the gym feeling as if I have had a proper workout. Zero come down. No idea what they are like when it comes to come down to want to sleep, as I always work out at 6am so easily worn off by bedtime for me.
Great product though.Goes Well With:Anything

Excellent product

I have used some other products like this, but they have not really worked for me. I use these along side a strict diet and I go to the gym every day. The energy boost in these are great i find myself doing more reps in my training and feel more energetic during the day. I have noticed a difference in my appearance, better than I would have without these and its only been 1 week. I found at the beginning that taking one before bed is not a great idea, as i lay in bed trying to get to sleep and not being able to. so I take two in the morning before breakfast and then two before my pre gym meal.Goes Well With:Water

Poor Product

After using Thermopure for a month and finding them to be really effective I decided to use this product to see even better results. Just over a month in and i`ve found them to be truly useless you would expect them to be more potent than thermopure but a total waste of money and some of my results reversed. Poor product and after contacting My Protein they are not interested.....
Stay away...

Waste money!

Bought 2 pack of them to test how they work, and after 1 month big disappointed. That product completly not help to warm up or anything. My opinion is waste money! Thermospeed or other is better. Don't buy this product, otherwise you lose your money.

Wish it had the effects on me like it did with others!

I took the recommended doses 4 a day, my diet was clean. I go gym regularly. 6 days a week and have been for the last 5 years, I'm not one of these guys that go there to socialise I really enjoy having a planned workout and seeing progress. It's gotta be said these didn't have much of an effect on me. The only thing I noticed is that I was pooing more but as far as my body fat it barely dropped. It did a bit because I was doing more cardio than ever but the product itself I don't feel like it assisted. As far as digestion, I never experienced any problems nor bloating. As far as other products like protein and amino, they taste great.Goes Well With:Any drink, It's a capsule!

Great product

Thermostat extreme

I've used thermopure before and it worked for me so I thought I'd try these, happy to say these work as well. I take two about thirty minutes before a session and find that I get a better workout from them the majority of the time. I've tried quite a few pre-workout powders and the Thermopure range are by far the best I've used .I train four times a week with weights for the past twenty odd yearsGoes Well With:Lucozade zero

Irritated stomach

I've used thermopure before and they worked really well. Having tried the extreme my stomach became irritated and sore for about two week. I thought I had an ulcer but after my stomach was back to normal I tried these again and the same thing happened. Sore swollen irritated stomach. I don't have any issues with eating spices food etc but I assume it's to do with the cayenne pepper being an ingredient.
